RedDots: Magnetic field of the nearby active M dwarf GJ 729, and a search for companions

E. L. Brown, S. V. Jeffers, S. C. Marsden +5

M dwarfs are prime targets for discovering exoplanets, and the nearest M dwarfs to the Sun provide among the best opportunities for follow-up detailed exoplanet characterization. G…

Multiwavelength Campaign Observations of a Young Solar-type Star, EK Draconis. III. Comparison between Starspot Mapping, Zeeman Doppler Imaging, and Multiwavelength Variability

Kai Ikuta, Kosuke Namekata, Pascal Petit +12

Recent simultaneous multiwavelength observations of a nearby young solar-type star EK Dra in the optical, H spectrum, and X-ray, have provided evidence for stellar prominence er…

The magnetic and spin-down properties of slowly rotating fully convective M dwarfs

Victor See, Louis Amard, Stefano Bellotti +19

The evolution of the magnetism, winds and rotation of low-mass stars are all linked. One of the most common ways to probe the magnetic properties of low-mass stars is with the Zeem…

A BCool survey of stellar magnetic cycles

S. Bellotti, P. Petit, S. V. Jeffers +6

The magnetic cycle on the Sun consists of two consecutive 11-yr sunspot cycles and exhibits a polarity reversal around sunspot maximum. Although solar dynamo theories have progress…

Multiwavelength Campaign Observations of a Young Solar-type Star, EK Draconis. II. Understanding Prominence Eruption through Data-Driven Modeling and Observed Magnetic Environment

Kosuke Namekata, Kai Ikuta, Pascal Petit +15

EK Draconis, a nearby young solar-type star (G1.5V, 50-120 Myr), is known as one of the best proxies for inferring the environmental conditions of the young Sun. The star frequentl…

The variable magnetic field of V889 Her and the challenge of detecting exoplanets around young Suns using Gaussian process regression

E. L. Brown, S. C. Marsden, S. V. Jeffers +3

Discovering exoplanets orbiting young Suns can provide insight into the formation and early evolution of our own solar system, but the extreme magnetic activity of young stars obfu…
